RAIL-LIFTING DEVICE.

To all whom it may concern: Be it known that I, Jnssn C. COOK, of Jeffersonville, in the count-y of Clark, State of Indiana, a citizen ofthe United States, have invented certain new and useful Improvements inRail-Lifting Devices; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appert-ains to make and use thesame.

In the art of timber impregnation, as with creosote, the timber is runinto the creosotingcylinder on rails from a track system in the yard,the track within the cylinder being connectible with the yard track byan approach track or rail section which must be removed from the path ofswing of the cylinder door to permit of the cylinder being closed.

It is the object of this invention to provide a simple and durablemounting for the removable track section whereby the same may be readilymoved to an inoperative position with little effort on the part of theoperator. 1

The invention further resides in the provision of a vertically swingingtrack section, counterbalanced to facilitate its upward movement, andhaving actuating means located to position the operator out of danger inthe event of an accidental lowering of the track section or breaking ofthe counterbalance. I

In the drawings, Figure 1 is a fragmentary side elevation of acreosoting cylinder depicting the removable track section in itsoperative position in full lines and in its inoperative position indotted lines; and Figure 2 is a top plan view thereof.

Referring more in detail to the accompanying drawing, the creosotingcylinder 1, which is equipped with the horizontally swinging door 2, isalso provided with rails (not shown) adapted to be joined to the yardrails 3 by the track section or door rails 4. These door rails are fixedat one end. to a horizontally journaled shaft 5 while their oppositeends are designed to be supported by the cylinder in alinement with thecylinder rails. The shaft is extended to one side of the rails and theouter extremity of such extended end is provided with a cam 6 which iskeyed to the shaft. In spaced relation to thecam 6,

an operating lever 7 is keyed to the shaft 5 for effecting turningofthe'shaft to raise or lower the rails. Lever 7 carries pawl 8 whichcooperates with a fixed quadrant 9 to lock the rails in any desireddegree of elevation. v

A counterbalance device is provided to assist the operator in liftingthe track section; An adjustable weight 10 is suspended from the outerend of a lever 11 which is fulcrumed on a short shaft 12, appropriatelyjournaled in bearings supported by the building walls (not shown), thelocation of this shaft being well above the shaft 5 so that the lever 11may swing in a vertical plane outwardly of the operating lever 7 Theshort shaft 12 also carries a second cam 13 to the sides of which theangle irons which form the lever 11 are bolted, these angle ironsconverging toward their oppo-- site ends to provide a braced structureand there connecting with a plate 14 from which the weight 10 issuspended. The cams 6 and 13 are shown in the form of interruptedcircular disks presenting substantially a onefourth part of its true orconcentric circumference, and the periphery of which circumference ispreferably grooved, as indicated at 14 and they are connected by aflexible member 15, herein shown as a cable, divided between its'endsand. having its sections joined by an adjustable take up device, such asa turnbuckle 16. The flexible member has its opposite ends anchored tothe irregular peripheral portions of the cams 6 and 13 beyond theconcentric circumference portions as indicated at 16 thus allowing theflexible member to slide over the'cam portions in the operation of thecounterbalance device.

In operation, when it is desired to lift the approach track section fromthe path of swing of the cylinder door, the operator manipulates thelever 7 to effect a clockwise rotation of the shaft 5 which elevates thedoor rails 4 to an upwardly inclined position, such as is indicated inFigure 1, where they are held locked by the cooperation of the pawl 8and its quadrant 9. The manual effort on the part of the operator ismaterially assisted by the counterbalance device which exerts acontinuous force tending to lift the rails. The counterbalance weightand the lever 7 are spaced sufficient: ly far from the rails to provideroom between the lever and the i ails for theiopteto o cupy-W h uendange ing hi self in the event of accidental brenkageof h rail 9 t e r0 atin m c anismiftertlie k lo01-2 has een opened therails 4: are-then"lowered 'to "the -fi111 line position by a counter-clockwise movementof the shaft and lever 7, whereby the yard and cylinder mils areconnected formovingthe timber-carrying trucks to and from the 0y] index.
